Mobile Vibration

You can absolutely add a small vibration (haptic feedback) when a player taps or clicks a GameObject in Unity. The exact method depends on the platform you’re targeting, but the setup is straightforward.

Below is a clean, reliable approach for mobile (Android/iOS) and a fallback for PC (no real vibration, but you can simulate with gamepad rumble).

📱 Mobile Vibration (Android & iOS)

Unity provides a simple built‑in vibration API through:

Handheld.Vibrate();

✔️ Step 1: Add a script to your clickable GameObject

using UnityEngine;

public class TapVibration : MonoBehaviour
{
    private void OnMouseDown()
    {
        // Trigger vibration
        Handheld.Vibrate();
    }
}

Notes

• Works on Android automatically.
• On iOS, vibration works only if the device supports it.
• OnMouseDown() works for 2D and 3D objects with a collider.

🎮 Optional: Stronger / Custom Vibration (Android Only)

If you want more control (duration, intensity), you can use Android’s vibration API:

using UnityEngine;

public class TapVibration : MonoBehaviour
{
    AndroidJavaObject vibrator;

    void Start()
    {
        if (Application.platform == RuntimePlatform.Android)
        {
            AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            AndroidJavaObject activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
            vibrator = activity.Call<AndroidJavaObject>("getSystemService", "vibrator");
        }
    }

    private void OnMouseDown()
    {
        if (Application.platform == RuntimePlatform.Android)
        {
            vibrator.Call("vibrate", 50); // 50ms vibration
        }
        else
        {
            Handheld.Vibrate();
        }
    }
}

🕹️ PC / Gamepad Vibration (if using controller)

If you want vibration on a connected controller:

using UnityEngine;
using UnityEngine.InputSystem;

public class TapVibration : MonoBehaviour
{
    private void OnMouseDown()
    {
        if (Gamepad.current != null)
        {
            Gamepad.current.SetMotorSpeeds(0.3f, 0.3f);
            Invoke(nameof(StopVibration), 0.1f);
        }
    }

    void StopVibration()
    {
        Gamepad.current?.SetMotorSpeeds(0, 0);
    }
}

🎯 Quick Setup Checklist

• Add a Collider2D or Collider to your GameObject.
• Add the script to the same GameObject.
• Make sure your scene has a Camera with a Physics Raycaster (for UI) or just a normal camera for 2D/3D objects.
• Test on a real device — vibration doesn’t work in the editor.

If you want, I can help you:

• Trigger vibration only on UI buttons
• Add cooldown so vibration doesn’t spam
• Use the new Input System for touch detection
• Add haptics for iOS using the Taptic Engine

Just tell me what style you want your game to feel like.
